Turning Fruit into Power Free Resource – STEM Scholars Hub

This activity explores the fascinating concept of generating electricity using everyday materials, providing students with hands-on insight into energy conversion. By creating a simple lemon battery, students observe how chemical energy stored in the lemon’s citric acid is transformed into electrical energy that can power small devices like LEDs. This experiment introduces foundational concepts in electrochemistry, including oxidation-reduction reactions, electron flow, and the role of electrodes and electrolytes. Students also learn how connecting multiple cells in series increases voltage, reinforcing real-world applications of batteries and energy sources.

This topic is ideal for students, teachers, and parents/guardians to explore the science of electricity and energy in a hands-on, engaging way. It is perfect for class demonstrations, small group experiments, homework, independent practice, or enrichment activities. Answer keys and supporting materials are provided for guided practice.
